Tobii is a company that specializes in eye-tracking technology, and it's just developed software that works with Windows 8. Using Tobii's "Eye control device" — essentially a fancy web cam — the software can tell which parts of the screen your gaze is focussed on, with enough precision to detect which app you're interested in launching.

Tobii claim to be able to emulate every swipe motion available on Windows 8, too. While it doesn't sound practical for use with a phone or tablet, it makes sense for touch-screen desktops, because reaching out and touching your monitor still feels a bit weird.
